vide means for reventing the deterioration of pine oil or isinfectants containing pine oil so that the germicidal power of the pine oil will not become impaired through age or for other causes. 7

I have discoveredthat disinfectants containin pine oil as the chief germicidal 7 agent ecome greatly weakened in the course a few months after manufacture. The property of the pine oil or disinfectant containing the same to kill germs and bacteria will become greatly lessened, even after the composition is bottled, and especially if it is exposed to light. This deterioration is due to a gradual chemical changein the pine oil and the change is one of oxidation. Pine oil as referred to in this patent is a general term given to certain fractions from the terpentine distillation of waste wood of; the long leaf southern pine but'is understood to mean any pine oil from any pine by this or similar rocesses. mixture of many essential oils of theterpineol family but the'essential constituent is alpha terpineol and is probably the optically active laevo modification of a terpineol. Terpineol is an unsaturated alcohol and being unsaturated oxidizes readily, terpineol peroxid bein one compound formed by its oxidation. ine oil ranges in density from .9291 to .9583 at 15.5 C., acid value 0.17 to 0.73, iodin value 118.4 to 173.9, flash 145 to 176 F. Average analysis-carbon 79.00%, hydrogen 11.2%, oxygen 9.8%. Pure terpineol analysis-carbon 77.85%, hydrogen- 11.77%, oxygen 10.38%.

A soluble pine oil'disinfectant is any disinfectant which is soluble in water or produces when poured into water a subdivision of the oil such as is characteristic of emulsions as to be considered soluble in water and containing pine oil in all proportions manufactured by the steam or solvent process, emulsified with saponified rosin,

saponified. fatty acids or any other emulsifying agent that would render the pine oil soluble 1n water as described above. I have discovered that there is a slow, accumulative oxidation of the ine oil with the formation of oxidation r0 nets of no or lesser germicidal ower t anpure pineoil, thus causing a wea ening of the germicidal power of the disinfectant. solving large quantities of oxygen. The action in the presence of water is therefore of dual character, the atmospheric ox en simultaneously producing eroxid of iydro- Pine oil is capable of dis-- gen which dissolves in t 'e-water-and oxiyielding oxidation productssuch as terp1neol" .peroxid, camphor resins, etc. This shows clearly why the disinfectant weakens much more rapidly than the pure pine oilalone.

The use of any 'reducin agent in any proportion at any time during the preparation of the disinfectant to prevent this oxidation, and subsequent germicidal weakening especially, the 'use of any. reducing sugar,,added at any time during the prepa ration, and in all proportions, namely, gra e sugar, or dextrose desi ated d-glucose y Fischer and known in its commercial form as starch sugar; also levulose, maltose or malt sugar, lactose, or milk sugar, invert sugar, etc. While any compound or mixture containing reducing sugars such as glucose,

honey, etc., or any of the reducing sugars named may be used, I prefer to use what is known commercially as rape sugar, and of this I employ about onealf of one per cent. by weight of the disinfectant or pine oil to be treated. It is also possible to prevent weakening of a pine oil disinfectant by the use of other reducing agents such as hydro gen, carbon monoxid, sulfur dioxid, and the sulfites, phosphites, hypophosphites, andthe ferrous salts of iron, tin, chromium and the like, in any proportions. These reducing agents may be added to the pine oil or disinfectant in any stage of its manufacture, and hence I do not wish to limit myself in any manner to the'process of incorporating the reducing agent therein, nor do I wish to limit myself in the use of any specific re-' ducing agent, but what I claim is:

1. composition of matter containing reducing sugar and pine oil made by the fractional steam distillation of pine wood.

2. A composition of matter containing pine oil and a reducing sugar.

3. A composition of matter containing pine oil and an invert sugar.
